Description

Technical Field

[0001] The utility model relates to the technical field of electric forklifts, in particular to a side plate structure of a battery frame of an electric forklift. Background Art

[0002] With the wide application of electric forklifts in industries such as logistics and warehousing, the performance of the battery frame structure directly affects the overall performance and safety of the forklift. Traditional battery frame structures often have problems such as poor heat dissipation, difficult installation and maintenance, and insufficient safety. For example, a large amount of heat is generated during the operation of the battery. If it is not dissipated in time, the battery temperature will rise, which will in turn affect the battery life and performance. At the same time, traditional frame structures require a lot of time and labor for installation and maintenance, increasing the operating cost. Therefore, it is particularly important to develop a side plate structure of a battery frame of an electric forklift with efficient heat dissipation, easy installation and maintenance, and safety and reliability.

[0003] The Chinese patent discloses a vehicle battery frame assembly (publication number: CN 211195826U), which includes several layers of battery frames for placing batteries. The bottom layer of the battery frame is fixed on the vehicle frame through supports. The supports include two support seats arranged under the bottom layer of the battery frame. Connecting plates for connecting with the vehicle frame are arranged at both ends of the support seats. The connecting plates are in an "L" shape. The vertical side of the connecting plate is fixed to the end face of the support seat. However, this kind of battery frame has problems such as poor heat dissipation, difficult installation and maintenance, and insufficient safety. Therefore, a side plate structure of a battery frame of an electric forklift is needed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages of the existing battery frame, such as poor heat dissipation, difficult installation and maintenance, and insufficient safety, and to propose a side plate structure of a battery frame of an electric forklift.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows: A side plate structure of a battery frame of an electric forklift described in the utility model includes connecting side plates, and is characterized in that: a hoisting support plate is arranged on one side of the connecting side plates. The number of the connecting side plates and the hoisting support plates is 2 each and they are arranged correspondingly. The connecting side plates and the hoisting support plates are combined to form a frame body. An exhaust fan is arranged at the bottom of the inner wall of the frame body, and a separating component is arranged above the exhaust fan. Through the corresponding arrangement of the connecting side plates and the hoisting support plates, the overall strength and stability of the frame are enhanced, which is convenient for hoisting operation.

[0006] Preferably, the separation component includes a battery protection frame. The number of the battery protection frames is 6 to 8, and they are arranged in an equidistant array. An insulating fireproof board is provided between each of the battery protection frames. The equidistant array arrangement of multiple battery protection frames not only provides effective battery protection but also optimizes space utilization, making the layout of the battery pack more compact and orderly. The presence of the insulating fireproof board significantly improves the safety of the battery pack, prevents short circuits and fire accidents, and ensures the safety of the whole vehicle and the surrounding environment.

[0007] Preferably, heat dissipation holes are provided on the outer walls around the insulating fireproof board. The number of the heat dissipation holes is 10 to 12, and they are arranged in an equidistant array. The provision of the heat dissipation holes increases the heat dissipation area of the insulating fireproof board, helps to dissipate the heat generated by the battery in time, keeps the battery within an appropriate working temperature range, thereby improving the performance and lifespan of the battery. The equidistant array arrangement ensures the uniformity and efficiency of heat dissipation and avoids the occurrence of local overheating.

[0008] Preferably, the top of the hoisting support plate is of a trapezoidal structure and is slightly higher than the connecting side plate. Hoisting holes are provided on the top of the hoisting support plate. The number of the hoisting holes is 2 and they are arranged correspondingly. The trapezoidal hoisting support plate improves the stability and load-bearing capacity of the frame, making the hoisting process more stable and reliable. The two correspondingly arranged hoisting holes facilitate the installation and use of hoisting equipment, improving the efficiency and safety of hoisting operations.

[0009] Preferably, a temperature sensor is provided on one side of the inner wall of the hoisting support plate. The temperature sensor can monitor the temperature change of the battery in real time, providing a basis for the adjustment of the cooling component, thereby realizing precise control of the battery temperature. Through the application of the temperature sensor, the usage efficiency and lifespan of the battery can be further improved, and the failure risk caused by excessive temperature can be reduced.

[0010] Preferably, clamping grooves are provided at the top around the inner wall of the frame body. Clamping plates are provided in the clamping grooves. The number of the clamping plates is 4 and they are arranged correspondingly. The provision of the clamping grooves and the clamping plates provides an additional fixing effect and enhances the overall stability of the frame. This design enables the frame to better disperse energy when subjected to external impact, improving the impact resistance. At the same time, it also facilitates the assembly and maintenance of the frame, improving production efficiency and maintenance convenience.

[0011] The advantages of the present utility model are as follows:

[0012] By setting up an exhaust fan and optimizing the design of the frame structure, the present application effectively improves the heat dissipation efficiency of the battery, keeps the battery within a suitable operating temperature range, and extends the service life of the battery. The application of the battery protection frame and the insulation fireproof board significantly improves the safety of the battery pack, prevents short circuits and fire accidents, and provides a more reliable safety guarantee for the whole vehicle and the surrounding environment. The design of the hoisting support plate enables the battery frame to be easily hoisted by a crane, facilitating installation and replacement. At the same time, the modular design of the battery protection frame also simplifies the maintenance and replacement process of the battery, reducing the maintenance cost and time. The reasonable space layout and compact design enable the battery frame to achieve the maximum battery capacity configuration within a limited space, improving the overall performance of the electric forklift.
